确定动物行为中可重复差异的程度以及影响行为表达的因素对于理解个体适应性和种群过程非常重要，从而有助于物种保护。然而，很少有人知道物种之间的行为差异的可重复性的变化的原因，因为很少有比较研究进行检查的可重复性的行为差异在其自然生态环境中的个人。本实验以两种亚热带特有的银莲花鱼--双锯鱼Amphiprionmccullochi和A. latezonatus在豪勋爵和北孤群岛，澳大利亚，我们进行了一个在现场的人格特征的比较分析，研究的重复性大胆，社交和侵略以及潜在的作用，环境和社会因素的行为表达。对于.只有大胆和攻击性是高度可重复的，这些行为形成了行为综合征。对于. latezonatus，没有三个行为是可重复的，由于行为的低个体间的变化。我们认为，更苛刻和更多变的环境和社会条件下经历的A。latezonatus导致行为的可重复性降低，与A.它们通常栖息在更稳定的泻湖礁环境中。此外，组的大小和大小排名，而不是最近邻距离和海葵大小，影响这些行为在这两个物种的表达，这表明行为的变化是更敏感的社会环境因素。总体而言，这些密切相关的物种之间的重复性差异可能反映了对对比环境和社会条件的适应，尽管必须考虑其他解释。这两种特有的海葵鱼之间的行为一致性的差异可能会导致他们的弹性在未来的环境或社会变化的差距。
Determining the extent of repeatable differences in the behavior of animals and the factors that influence behavioral expression is important for understanding individual fitness and population processes, thereby aiding in species conservation. However, little is known about the causes of variation in the repeatability of behavioral differences among species because rarely have comparative studies been undertaken to examine the repeatability of behavioral differences among individuals within their natural ecological settings. Using two species of endemic subtropical anemonefishes, Amphiprion mccullochi and A. latezonatus at Lord Howe and North Solitary Islands, Australia, we conducted an in situ comparative analysis of personality traits, examining the repeatability of boldness, sociability and aggression as well as the potential role of environmental and social factors on behavioral expression. For A. mccullochi, only boldness and aggression were highly repeatable and these behaviors formed a behavioral syndrome. For A. latezonatus, none of the three behaviors were repeatable due to low-inter-individual variation in behavior. We suggest that the harsher and more variable environmental and social conditions experienced by A. latezonatus have resulted in reduced repeatability in behavior, in contrast to A. mccullochi which typically inhabits a more stable lagoonal reef environment. Additionally, group size and size rank, rather than nearest-neighbor distance and anemone size, influenced the expression of these behaviors in both species, suggesting that behavioral variation was more sensitive to social than environmental factors. Overall, differences in repeatability between these closely related species likely reflect adaptations to contrasting environmental and social conditions, although alternative explanations must be considered. The differences in behavioral consistency between these two endemic anemonefishes could lead to disparity in their resilience to environmental or social change in the future.
